I am getting the following error when trying to save a structured entry:

Could not generate a unique URI based on the URI format.

Title of entry is: Hells Gate Mud Bath & Spa

Slug: hells-gate-mud-bath-spa

The entry title is 100% unique also. Any ideas what is causing this and what the fix may be?

Turns out the error was because {slug} was missing from the Section Setting: Entry URI Format
